Se evaluó la sustentabilidad ecológica de la cacería selectiva del borrego cimarrón (Ovis canadensis mexicana) en las Unidades de Manejo para la Conservación de la Vida Silvestre (UMA) del estado de Sonora, México; considerando como variable el puntaje de la cornamenta. Se utilizaron animales cazados bajo los esquemas de manejo extensivo e intensivo. Los datos se analizaron mediante regresión lineal, prueba t de student de una cola, análisis de clúster de dos tiempos y un sistema de clasificación por medio de algoritmo k-means. Aunque la prueba de t no mostró diferencias (p > 0.05), los resultados indican, que en la predicción de cacerías, las UMA intensivas registraron tendencias superiores (+4.253 puntos en la cornamenta). En los esquemas de manejo, el análisis clúster indica que el agrupamiento 1 clasificado como UMA calidad 10 fue el más sobresaliente, el cual agrupó a la UMA Isla Tiburón de manejo intensivo. En contraparte, el agrupamiento 10 clasificado como UMA calidad 1, incluyó los borregos Cimarrón peor dotados, teniendo siete representantes; seis de ellas extensivas (Big Horn Safari, El Cimarrón, Hueverachi, Sierra del Viejo, Los Mochos, Punta de Sirios) y sólo una de manejo intensivo (El Sacrificio). El análisis de clasificación de cornamentas expuso que los borregos cimarrón cazados en Sonora, pueden alcanzar puntajes de 180.0742 ± 5.91.
This research was conducted in bighorn sheep (Ovis canadensis mexicana) to assess the ecological sustainability of selective hunting in UMA registered in Sonora, Mexico; considered as a variable score antlers. In this research hunted animal specimens under two management schemes were used: extensive management (free living) and intensive management (protected with special perimeter fences). Data were analyzed using linear regression method, t-student test, cluster analysis of two-strokes and a classification system using k-means algorithm. Although the t test did not show significant differences (p > 0.05), the results show that in predicting hunts, intensive UMA tend to be highest (4253 antler points and 1647 error points). Comparing management schemes, cluster analysis indicated that cluster 1 rated as UMA Quality 10 was the best, which grouped the UMA known as Tiburón Island as the only representative of the extensive management. In contrast, the group 10 ranked as UMA Quality 1 included the bighorn sheep which were the worst evaluated; it had also seven representatives; six of them were in UMA under extensive management (Big Horn Safari, El Cimarron, Hueverachi, Faldas de la Sierra del Viejo, Los Mochos, Puntas de Sirios) and only one was under intensive management (El Sacrificio). Analysis of antlers classification shows that bighorn sheep hunted scores in Sonora reached 180.0742 ± 5.91 points.
